I'm due to have my period early next week but it's usually give or take a few days and I'm planning on starting the pill on the first day of it. My boyfriend and I have been using condoms in the meantime. Last night when he came, I got some on my hand but I think it probably rubbed off on the sheets. Really soon afterwards I inserted a finger into my vagina (not even sure if it was the same hand) but now I'm quite scared that some trace sperm has gotten in. Is there a good chance I could be pregnant?

It's very unlikely lovely; sperm normally dies if exposed to air for more than ten minutes anyway. On the other hand, if you are worried, just pick up a pregnancy test from your local pharmacy to put your mind at rest.
